Bug 19361: (QA follow-up) Make sure "Not an authorised value" appears in the pull down

This is to make sure that the small icon with the additional tooltip
style explanation is not as easily missed.

Also updates text slightly:
* Pull downs: "X (Not an authorised value)"
* Tooltip: "The current value X is not configured for the authorised value category controlling this subfield"

Switches from exclamation triangle to the more "alerting" exclamation-triangle :)
